Abstract
Smoke of a plain 85 mm cigarette, 2 types of cigars, a pipe with standard pipe tobacco, a pipe filled with cigarette tobacco, and a Syrian water pipe was analyzed for the mainstream particulate matter, nicotine, benzo[a]pyrene, and phenols. On the basis of equal weights of tobacco consumed, cigarettes gave the highest yields of both nicotine and particulate materials, with lesser amounts, in decreasing order, obtained from an American-type pipe, cigars, and an oriental water pipe. The highest value from 100 g tobacco for benzo[a]pyrene, 27.0 μg, and phenol, 68.7 mg, was found in the smoke of a pipe filled with standard pipe tobacco. A pipe filled with cigarette tobacco yielded benzo[a]pyrene, 10.5 μg, phenol, 21.2 mg; cigarette smoke, benzo[a]pyrene, 7.8 μg, phenol, 25.4 mg; cigar smoke, benzo[a]pyrene, 4.0 and 5.1 μg, phenol, 7.4 and 10.7 mg, with the lowest values for the smoke from an oriental water pipe, benzo[a]pyrene 1.7 μg, phenol, 1.8 mg. The water-filled oriental pipe retained about 90 percent of the phenol of the original smoke. Particulate matter, nicotine, and benzo[a]pyrene were retained to a lesser degree by the water (about 50%). Increased puff frequency resulted in higher yields of all 4 groups of compounds in the mainstream smoke. Values at 2 puffs per minute frequency ranged from 50 to 120 percent higher than those at 1 puff per minute when the other smoking factors were held constant. Since biological tests and comparisons of the carcinogenicity of the condensates of cigarettes, cigars, and pipes have previously been carried out on equal weights of condensate, the analytical results of this study were compared in the same manner. One g of the smoke condensates from 85 mm plain cigarettes, 2 types of cigars, and a standard pipe contain 1.25, 3.6, 3.9, and 6.0 μg benzo[a]pyrene, respectively. The corresponding phenol values were 4.1, 6.7, 8.2, and 15.0 mg per 1 g smoke condensate.
